A
A grave of a man dating back to around 2300 BC was found by archaeologists in England On May 3, 2002. Buried with him were the tools of a hunter or warrior. There was a bone pin that may have been from a piece of clothing such as a leather coat. He carried a copper knife on his breast. The most amazing find was two gold earrings. That would have made him a man of distinction. Only a few centimeters from his head were two pots made of clay, tools and materials to make arrows, a bow and a dozen arrows for hunting and a second, smaller copper knife. Next to them lay a cushion stone, upon which the man could work metal.
His grave is the richest of any found from that period, because this man was buried with two gold earrings which are the oldest gold ever found in Britain (dated to 2470 BC). Besides, he was buried three miles from Stonehenge. Archaeologists tend to believe he was a member of a powerful class who might have organized the construction of Stonehenge.
Stonehenge was begun around 3000 BC. In about 2300 BC the huge stone circles were built. The biggest stone weighed approximately 20 tons. But the smaller blue stones, still weighing 4 tons on average, came from west Wales. It is not yet known how these were conveyed over a distance of 380 km. It is also a mystery how early man was able to construct Stonehenge without the use of modern construction machines and lorries.
He is an example of people who brought culture and new techniques from the European mainland to Britain. In terms of technical development people were going from the Stone Age to the Bronze Age and then to the Iron Age.
56. Which are not included in the things that are found in the grave of a man? A. Tools, a bone pin, a bow and a cushion stone B. A copper knife and two gold earrings.
C. Two pots, arrows and materials to make arrows. D. some chicken and grains.
57. The man buried in the grave might be ______ at that time.
A. A poor man B. a kind-hearted man C. a rich man D. an ordinary man 58. Why is the man buried in the grave called the \"king of Stonehenge\" ? A. He was buried three miles from Stonehenge. B. He had the oldest gold ever found in Britain.
C. He might be a member of a powerful class who might have organized the construction of
Stonehenge. D. All of the above. 59. We can infer that _______ . A. how Stonehenge was built B. the King of Stonehenge was from France C. Stonehenge was built through several ages D. Stonehenge was built because of war 参考答案 DCDC

In Jurassic Park, DNA was used to clone dinosaurs, which was kept for tens of millions of
years. The scientists find trouble, however, when they realize that the cloned creatures are smarter and more dangerous than expected. That’s nothing more than a fiction. But could we really clone endangered animals?
To date, the most successful attempt to do so was the cloning of a gaur, a rare ox-like animal from southeast Asia. Scientists used a cow to bring the cloned baby gaur, named Noah. Two days after birth, however, Noah died from a common bacterial infection. Other endangered species that may be cloned include the African bongo antelope (邦戈羚羊), the Sumatran tiger, the cheetah (猎豹), and the giant panda.
Next, could we really clone extinct animals?
In theory? Yes. To do this, you need a well-kept source of DNA from the extinct animals such as wool mammoth (毛象), Tasmanian tiger, or even dinosaur, and a closely related species, still living, which could serve as a surrogate mother.
In reality? Probably not. On the one hand, it’s not likely that extinct animals’ DNA could survive undamaged for such a long time. Cloning extinct animals as wool mammoth, Tasmanian tiger, or dinosaur is much more difficult due to the lack of properly well-preserved DNA. On the other hand, for example, a gaur can have a cow as a surrogate mother, definitely not a monkey. But what about an extinct animals as unique as the panda? What species could possibly serve as a surrogate mother?
Cloning presents many exciting possibilities. However, even if extinct animals are brought back, they could not survive in today’s world. Not only do most extinct animals have no habitat to live in, but the other plants and animals they depended on for food may also be gone as well. 60. It can be learned from the text that ________.
A. scientists have cloned the African bongo antelope B. both the cheetah and the giant panda live in Asia C. the gaur lives in Asia and is endangered D. the gaur is an extinct species
61. The underlined words \"a surrogate mother\" probably refer to a female who ______. A. contributes its eggs to another female B. gives birth to a baby for another female C. gives birth to a baby of its own D. cannot give birth to a baby
62. The difficulty in cloning an extinct species is the lack of ______. A. both the well-preserved DNA and plants to live on B. both the habitat to live in and the well-preserved DNA C. both habitat to live in and plants to live on D. both the well-preserved DNA and a surrogate mother 63. In the author’s opinion, it is possible that ______. A. some extinct species may be cloned, but not survive B. extinct species may be cloned and easily survive C. a gaur can have a monkey as a surrogate mother D. all the extinct species may be cloned CBDA
